TELEPHONE CABLE-TERMINAL.

Specification of Letters Patent.

Patented July 23, 1907.

Application filed August 28, 1906. Serial No. 332,408.

To all whom it may concern:

Be it ,known that I, EDWARD CHARLES honor, a citizen of the UnitedStates, residing at Santa Barbara, in the county of Santa Barbara andState of California,

have invented a new and useful Telephone Cable- Terminal, of which thefollowing is a specification.

This invention relates to terminal cables or boxes of that general classdesigned for attachment to a telegraph pole or. other suitable supportand used for distributing overhead conductors or wires to the severaltelephone, telegraph or other electrical instruments at any particularstation.

The object of the invention is to provide a distributing box having amoisture proof compartment for the reception of the terminals of thelead covered cable, and further to provide means for preventing'theentrance of moisture at the point where the cable enters thecompartment.

A A further object is to formthe wire-receiving compartmentwith aremovable wall or cover whereby an additional contact or terminal platemay be placed in position on the opposite side of the compartment, .thus

- doubling the capacity without increasing the size of the'box.

A stillfurther object of the invention is to generally improve thisclass of devices so as to increase their utility, durability andefiiciencyl Further objects and advantages will appear in the followingdescription, it being understood that various changes in form,proportions and minor details of construction may be resorted to withinthe scope of the appended claims.

In 'the accompanying drawings forming a part of thisspecificationLFigure his a longitudinal sectional view of a cabledistributing box constructed in accordance with my invention showing thesame in position on a telegraph pole. Fig. 2 is a similar view showing aportion of the rear wall of the compartment broken away to expose theterminals of the cable wires. Fig. 3 is a transverse sectional viewtaken on the line 33 of Fig. 1. Fig. 4 is a similar view taken on theline 4-4 of Fig. 3. Fig. 5 is a transverse sectional view showing therear wall of the compartment removed and an additional contact plateplaced in position thereon, 1

Similar numerals of reference indicate corresponding parts in all of thefigures of the drawings.

The improved distributing box or terminal head is suitable support andin the present instance is shown supported in position on atelegraphpole 5 by means of a supporting bracket 6 one end of which is bolted orotherwise rigidly secured to the pole, as indicated at 7 while itsopposite end is bent at right angles thereto and provided with aplurality of laterally extending arms 8 which are riveted, bolted orotherwise rigidly secured to the base 9 of a casing or housing 10.

The casing or housing 10 is preferably cylindrical in shape, as shown,and is normally supported on a flange 11 extending laterally from thebase plate 9, said casing being closed at its upper end and providedwith a terminal handle 12 by means of which the casing may beconveniently positioned on or removed from the base. i

Arranged within the casing or housing 10 is a water proof compartment orchamber 13 the end walls 14 of whichare bolted, soldered or otherwiserigidly secured to the plate 9 and provided with laterally extending"flanges 15.

Detachably secured to the flanges 15 on one side of the end walls 14 isa removable plate 16 which forms a closure for one side of thecompartment 13, the opposite side of the compartment being normallyclosed by a plate 17 preferably formed of vulcanized fiber, rubber orother suitable insulating material, as shown.

The interior walls of the compartment 13 are lined with oil paper orother suitable water proof material 18, and interposed between theinsulating plate 17 and the adjacent flanges 15 is a rubber gasket 19retained in position by bolts or similar fastening devices 20 passingthrough the perforations in the flanges 15.

Extending through an opening 21 in the base 9 is a lead covered cable 22the terminals of which are arranged within the compartment 13 andconnected to the binding posts 23 of suitable contacts 24 disposed onthe opposite side of the plate 17, and to which are connected thedistributing wires 25. The distributing wires, 25 extend downwardlythrough an opening 26 formed in the base plate 9 and are connected inany suitable manner to the wires or conductors leading to the severaltelephone, telegraph 01 other.electrical'instruments to be operated. Thecontacts 24 are each preferably formed of a single piece of metal havingan intermediate portion struck up to form an integral hook 27 and oneend thereof bent upon itself to form a spring clamping member 28 adaptedto engage the terminals of the distributing wires 25 whereby the wiresmay be clamped in position on the plate 17 without the employment ofbinding screws and similar fastening devices.

Extending longitudinally of the compartment 13 at the bottom thereof andsecured in any suitable manner to the plate 9 are parallel verticallydisposed metal strips 29 which form rests or supports for the plates 16and 17, respectively.

Spaced laterally from the metal strips 29 are inclined flanges 30defining wedge shaped sockets 31 for the reception of the adjacent endsof the plate 17 thereby to assist in retaining'said plate in position onthe bottom of the casing.

Extending transversely across the compartment 13 land soldered orotherwise rigidly secured to the metal,

strips 29 is a partition 32 defining a chamber-33 for thereception of aquantity of bees wax, paraffin wax or other suitable water proofmaterial which surrounds the cable 22 at its point of entrance into thecompartment 13 andthus prevents the entrance of moisture to saidcompartment.

When it is desired to increase the capacity ofthe cable.

boxes the plate 16 may be removed and an insulating plate 17 similar inconstruction to the plate 17 placed in position on the adjacent flange15, as best shown in Fig. 5 of the drawing. When two of the insulatingplates are used the terminals of the auxiliary cable will extend throughan opening 34 in the bottom of the plate 9 and which is normally closedby a cover 35, the distributing wires of the auxiliary cable beingattached to clips 24 similar in construction to the clips 24 and thenceextended downwardly through an opening 26 to the telephone or otherelectrical instruments. Attention is here called tothe fact that one rowof each set of contacts24 end 24 is mounted on a suitable insulatingstrip 36 secured to the adjacent plate so that some of the contacts maybe off-set with respect to the others and thus permit the terminals ofthe distributing wires to be readily connected with said contacts Theboxes may be used for distributing all of the pairs of wires in thecables at any particular point or for bring-j ing them into the box andcarrying the same pairs out in another cable to another distributing boxso as to permit of multiple cable work. The boxes may be made indifferentsi zesand shapes so as to accommodate any Having thus describedthe invention what is claimed is:.

1. In a distributing box for cables, a casing, a moisture proofcompartment arranged within the casing, flanges disposed on each side ofthe compartment, spaced members arranged within the casing and forming asocket a plate seatedlin said socket and bearing against the adjacentflanges, said plate constituting one wall of the compartment and havinga plurality of contacts secured thereto for" engagement with the cablewires, and distributing wires operatively connected with said contactsand extend- .ing through the walls of the casing.

2. In a distributing box for cables, a casing, a moisture proofcompartment arranged within the casing and having its end walls providedwith laterally extending flanges, spaced members secured to the bottomof the casing and forming sockets insulatingplatea constituting the sidev walls of thecompartment seated in said sockets and each provided witha plurality of contacts, there being openings formed in the lower wallof the compartment and apertures formed in the bottom of the casing anddisposed one on' each side of said compartment, cable wires extendingthrough the openings in the bottom of the compartment and arrangedwithin said compartment for connection with the tei-minals of theinsulating plates, and distributing wires operatively connected with thecontacts ahd extended downwardly through the apertures in the bottom ofthe casing. Y

3. In a distributing box for cables, a casing, a. water connected withthe contacts and extending through the casing.

. In testimony that I claim the foregoing as my own, i have heretoafiixed my signature in the presence of two witnesses.
